--- Comment #1 from Kevin A. McGrail <km...@apache.org> ---
Unfortunately, the science backs up that the TLDs are problematic. If a false
positive is generated on a legitimate email with stock rules on a current
version of Apache SpamAssassin, that's a different issue.  

Not much we can do with this trouble report other than agree with you that the
.space TLD is problematic.

Those rules all passed automated QA and had their rule scoring set by a genetic
algorithm designed to correctly classify emails.

Bayesian naive theory is also used along with DKIM, DMARC and SPF though DMARC
is newer for most people.

If you have a false positive, put an email up on pastebin and post on the users
mailing list.
